Another object is to provide such a sepa'rator having a plurality-of'radially spacedpassages-for leading ofi theseparated portion as soon as it is 'separatedr Inittingthe incoming liquid to flow directly to, the disk on'which: separation of thatpor tion-of the liquidtakes place without having to pass through the other disks.

A still further object is toprovide a novel methodfor separating different constituentsofa'liquid. I V Q Other objects and advantages will become apparent from the following" description the accompanying taken in connection with drawings, in which: I g Y Figure 1 is a vertical section through a separator bowl assembly embodying the features 80 ofthe invention,

Ina centrifugal creainseparator, the bowl assembly is adapted to be .inounted Jon the upper end of a drive shaft and to, 'be rotated at a high; constanthpeedthereby; In the cream separator constituting the present invention, the bowl assembly comprises: in gen- Q eral a central stem, a pluralityof'skimming' disks surrounding said stem, 1neansjformed on said stem for. introducing the' whole-milk directlytherefrom to eachdisk, andxtwo sets of creamexit passages througlrsaidfdisks,

said sets being radially spaced: from each .ratedand the other to catch the=cream less easilyseparated inorder to prevent it p'a'ss other, one to catch the cream easily. sepaing back through the incoming wholeinilk.

" As shown in the-drawings, a stem llOfisf" provided which is tubular"in .form and open, at its top; Abowl 11 having a' -conical botef' tom and iuptu'rned sides; is rigidly attached to the lower end of thejstem'so that the lat-xter projects centrally upward from thefbottom of the bowl 11. The'stem 10 is adapted to beseated'supon and driven by a'shaft (not ab V 1 1 shown) running ata high'rot ative'speed. A'

bow-l cover 12 having a conical shape is adapt y ed to close the bowl 11f with 'a liquid-tight seal therebetween and to be rigidly held by a nut 13 threaded to the topofthe.

lVithin 'the-lbowl'jll there are a plurality of conical skimming disks l4.(see Fig. 1) centrally apertured' to, surround the stem '10 and held' in axially spacedrelation to each i other." Covering the skimming disks 1413a dividing diskjl5 which, in conjunction i the stem 10 and with the bowl cover 12, pro; vides separate paths for the cream and skim} milk'respectively-to follow in passing out of the bowl.""

; The stem 10' being tubular and open-at its top forms an inlet through which whole-milk may be introduced'to thebowh On the side i 1 o f the stem; a plurality of radially extending wings 16 are formed (see Figs. land 2) each of which, at its upper end, has a radial orifice '17 communicating with the -in-' ly downward from the orifice 17 past all of. the skimming disks 14;. Thus, the whole-milk mayfipass front the iainterior L1 of the a stem through the orifices 17 andidown in the chain nels 18"freely and'without restriction toeach skimming disk 14; c T

around' the wings -1 6 (seeFigQ 2.), one wing ming disks willialways be assembled in the I I same relationto'the stem. Theapertur'es are offsuchdiameter that theedges thereof are radially sp aced' fronithe main bod} of the stem' to'form gapsQO therebetween constituting a first of cream exit passages. Thus,

; said creameXit passages are angularly spaced from thejorificesvl'i and are closer to the axis of rotation than the outerendsofsaid orifices.
